there is ample room. Tubular ducts n in the pillars '0 connect the channels m to the several gas-nozzles, so that the streams of gas are pre-heated by their passage through the structure of the regenerator.

In the case ofovens heated by means of generator gas, as 1s usual in gas-works, the,

To all whom it may concern: I Be it known that I, Hnmnron Koreans, a I citizen of the German Empire, and resident of 30 Isenbergstrasse, Essen-on-the-Ruln', l Germany, have invented new and usefull Improvements in Coking and Gas-Generating Ovens, of which the following is a specification. I ducts leading to the heating fines are liable This invention relates to coking and gas to become clogged with dust. The dust i-s6 generating ovens, and substantially consists principally deposited where the ducts branch in obviating the difliculty of arranging the oil from the distributing pipes, scales being gas distributingchannels in the brickwork, formed 011 .the walls of the ducts. The arby arranging the said channels below the rangement of,the distributingchannel m air-heater, instead of between the oven and in the plane of'the heating wall, and of the air-heater, and connecting them to the 1102- l several ducts 9'1 in the axes of the fines, enables the deposits to be easily removed by means of bars inserted through normally closed apertures g, which also serve for in-' spection of the gas-nozzles and access to the 7 dampers p.

.What I claim is 1. coking and gas generating oven, comprising a plurality of heating walls, in-' termediate cokin chambers, air preheating 7 chambers locatecI below the coking cham bers, waste heat chambers flanking the air preheating chambers, gas distributing channels located below the air preheating chamof the heating walls. This arrangementnot only has theadvantage that the gas distributing channels can be. constructed of a cross-section enabling them to be conveniently cleaned out when necessary, but also causes the heating gas to be pre-heated in the branch conduits leading upward through the structure of the air-heater, and the heat generated by the combustion is thus increased.
